The public service broadcaster was found to have committed a "major breach" of industry standards by omitting to mention that the presenter of a film about Gaza was the son of a Hamas administrator, as determined by regulatory body Ofcom.
An investigation by Ofcom into the documentary titled Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The head of the BBC had previously apologised, saying there had been "a serious error in relation to factual correctness".
The regulator has ordered the corporation to transmit a evening statement about its findings.
"Since this amounts to a significant violation of our rules, we are ordering the corporation to air a statement of our conclusions against it on the BBC's second channel at 21:00, with a date to be determined," it said.
'Risk to Damage Credibility'
The authority's statement declared: "Our investigation determined that the film's failure to disclose that the presenter's male guardian occupied a position in the Hamas-administered authority was substantially inaccurate.
"This implied that the audience did not have critical information which may have been very significant to their assessment of the voice and the information he provided.
"Trust is at the core of the relationship between a media organization and its audience, particularly for a national broadcasting corporation such as the British Broadcasting Corporation.
"This error had the possibility to undermine the significantly high levels of credibility that the public would have placed in a documentary produced by the BBC about the Israel-Gaza war."
The film was withdrawn from the online platform in last February after the narrator's personal associations were revealed, and in the month of July an broadcaster's internal assessment found it breached the corporation's editorial guidelines on factual correctness.
A corporation official commented: "The Ofcom ruling is in accordance with the findings of the corporation's inquiry, that there was a serious error in the programme in relation to the corporation's content standards on factual correctness, which aligns with regulation 2.2 of Ofcom's Broadcasting Code.
"We have apologised for this and we agree with the authority's determination in complete. We will adhere to the penalty as soon as the date and wording are confirmed."
